I’d say Germany is about 50:50 verbally, but also depending on use. If using the 12h clock, one wouldn’t say “2:17”, rather round to “quarter past 2”. The other half of people would use “14:17”. But also if talking about timetables or other occurrences where the rounding would be detrimental, 24h will be u.sed.

Writing, I would say is about 90% 24h clock, because it’s just faster. Here, the divide would be between digital time (“14:17”) and military time (“1417”).
